All of the giant planets of our Solar System, except Uranus, emit more energy in the long wavelengths than what they receive from the Sun in the short wavelengths. This excess of energy was generated in the early stages of the planetary formation and it is being radiated slowly to space as the planets keep […]
Almost four years after being launched to space, the Herschel Space Observatory ran out of helium the past April 29. This implied losing the ability to stay as close as possible to absolute zero (at about 2K, indeed) which also meant the death of the spacecraft, since this mission was designed to observe the universe […]
There are some science news that appear recursively in the media. Just to stick to my field of knowledge we could point to Mars’ water and habitability of extra solar planets. It is certainly great to have people reading about those topic, although some confusion seems to have settled down among public opinion. I am […]
Poles are truly interesting places for planetary scientists. On Earth, the southern pole and its low surface temperatures sustain a polar vortex, most famous for the related hole in the ozone layer. On Saturn, for example, both poles have astonishing structures, including a hexagonal wave in the northern hemisphere. Not surprisingly, Venus also has something […]
The Kepler mission is gazing at the Universe. Every little twinkle in more than 150,000 stars is being recorded since 2009, looking for planetary transits. And this will continue for at least three more years, giving us insight into the wondrous nature of the planetary systems in our galaxy’s vicinity. So far, we had witnessed […]
